Does the C++ compiler in C++Builder generate fast-enough code for your needs?

It is well known that the C++ compiler in C++Builder does not generate fast code. For example, compared to Visual Studio or g++, some of my image-processing algorithms take twice as long to complete (or more) when compiled in C++Builder. The same exact code.

So, for me, there are many parts of my code that I need to compile using a different compiler, and then relay the results back to C++Builder. Of course, the RAD capabilities of C++Builder make up for this deficiency, but I really wish the C++ team would begin to focus on speed.
